Complete diet for yabbies according to their growth stages

Of course, the success of your breeding activities relies in providing a complete diet for Yabbies (Cherax destructor).

In such a way to provide them with all the nutrients they need to grow out at a constant rate, healthy and with no nutritional deficiency.

As a matter of fact, this is the main prevention measure to take against diseases and consequently epidemics inside the tanks.

Particularly, this freshwater lobster has high calcium requirements, that are met either with an alkaline water (hardness: 8) and with calcium-rich food as well.

In fact, it’s common to detect a softening in the shell of individuals that aren’t correctly fed. Since they haven’t enough calcium supplies to complete the moulting process. It can even occur that their gills remain uncovered, because of this calcium deficiency.

But, don’t worry, it’s reversible. Just provide them with calcium-rich food and wait for them to moult again a pair of times. Such as cabbage leaves. But, overall, Snails both freshwater and land ones, that supply Yabbies with the correct amount of calcium they require. (And anyway they love them.) Only remember that the latter don’t sink. So that you must crack the shell before introducing them into the tank.

YABBY FEEDING BEHAVIOR

Indeed, never forget Yabbies, as all the crayfish, are bottom feeders. That is to say, they’re going to eat only sinking food. This is the reason why the veggies must be boiled or steamed.

And considered that on the market is very difficult to find available specific adult *crayfish dry food options, most of the breeders (like us) use sinking fish pellets. So much as rabbit or chicken feed alternatives.

While for Yabby juveniles, you can purchase Shrimp sticks that don’t contain artificial colorants (if you address your production for the food market).

Moreover, even if they’re omnivorous, their consumption of live animals is quite limited compared to the vegetable options. This is because they’re mainly (but not completely) herbivorous. Therefore, except snails, feed them with meat (i.e. pieces of chicken) a maximum of twice a week. Also because the uneaten food, decomposing itself, will pollute the water.

And for preventing it to happen, remember everyday to check the amount of food scraps they have left. In such a way to calculate how much food to give them. Especially when the temperature are lower than 20°C (68°F) and they gradually stop to eat. As well as when the females start mating.

In fact, the reason why all the females remain smaller than the males is that during the multiple broods they stop feeding themselves until after the release of the juveniles.

Anyway, for improving the beneficial effects of a complete diet for Yabbies it’s advisable to keep right levels of water turbidity. In other words, you enhance the frequency of their feeding activities, maintaining a constant coverage that makes them feel protected.
